When the display assembly 10 is in thelandscape mode B, a horizontal direction center line passing theassembly center C is referred to as a first center line L1, and avertical direction center line passing the assembly center C is referredto as a second center line L2. The assembly center C may be a center inhorizontal and vertical direction of the display assembly 10, or thecenter of gravity of the display assembly 10.

The rotation guide 50 may be spaced an eccentric distance d apart fromthe assembly center C. With the configuration, the display assembly 10may be rotatable with respect to a position deviated from the assemblycenter C.

FIG. 5 is a cross-sectional view showing a part of a configuration of adisplay apparatus according to an embodiment of the present disclosure.Hereinafter, the display apparatus 1 will be described with reference toFIGS. 1 to 5.

The mounting device 30 may include a rail 80. The rotation guide 50 andthe rail 80 are collectively referred to as a guide apparatus.

The rail 80 may cause the display assembly 10 to move in a straight linedirection. The rail 80 may be disposed on the rear surface of thedisplay assembly 10. The straight line direction may include ahorizontal direction and a vertical direction with respect to thedisplay assembly 10. In the current embodiment, a configuration in whichthe display assembly 10 is located in the portrait mode A and moves in avertical direction or along a second center line L2 through the rail 80will be described. However, the display assembly 10 may be positioned inthe landscape mode B, and move in a horizontal direction or along thefirst center line L1 through the rail 80.

The rail 80 may pass the assembly center C. That is, the rail 80 maypass the assembly center C, and be disposed along the second center lineL2. In the current embodiment, the rotation guide 50 spaced from theassembly center C may be disposed at one end of the rail 80, and theother end of the rail 80 may be located at the assembly center C. Withthis configuration, when the display assembly 10 is in the landscapemode B or in the portrait mode A, the assembly center C and thesupporting boss 42 may be placed on the same center line to stablysupport the display assembly 10. A boss stopper 86 may be disposed atthe other end of the rail 80 so that the supporting boss 42 is notseparated from the rail 80.

The rail 80 may limit a linear movement of the display assembly 10 whenthe supporting boss 42 is located on the rail 80. That is, the rail 80may include a pair of guide rails 82 to limit a horizontal movement ofthe display assembly 10.

The pair of guide rails 82 may restrict both sides of the supportingboss 42 to cause the display assembly 10 to move linearly. In thecurrent embodiment, the pair of guide rails 82 may restrict the upperand lower portions of the supporting boss 42, and extend in a horizontalmovement direction. That is, the pair of guide rails 82 may restrict theupper and lower portions of the supporting boss 42, and extend along thesecond center line L2. Since the rail 80 is movable in the horizontaldirection with respect to the supporting boss 42, the display assembly10 fixed to the rail 80 may also be movable in the horizontal direction.That is, the rail 90 may prevent the display assembly 10 from rotating.

The rail 80 may include a separation-preventing hook 84. Theseparation-preventing hook 84 may prevent the supporting boss 42 frombeing separated from the pair of guide rails 82. A pair ofseparation-preventing hooks 84 may be provided. An interval between thepair of separation-preventing hooks 84 may be smaller than that betweenthe pair of guide rails 82. Accordingly, the separation-preventing hooks84 may prevent the supporting boss 42 located between the pair of guiderails 82 from being separated from the rail 80.

The separation-preventing hook 84 may be formed convexly from thesupporting boss 42 located on the rail 80. The supporting boss 42 mayalso include a convex projection 45 convexly formed from the boss body43 to correspond to the separation-preventing hook 84.

The display assembly 10 may move linearly when the supporting boss 42 ispositioned on the rail 80, and may rotate when the supporting boss 42 ispositioned on the rotation guide 50. In other words, by separating aconfiguration for linearly moving the display assembly 10 from aconfiguration for rotating the display assembly 10, a configuration ofthe mounting device 30 for supporting the display assembly 10 may beminiaturized. In addition, even when a display mode (the landscape modeB and the portrait mode A) changes, the mounting device 30 may stablysupport the display assembly 10.

The rotation guide 50 may be disposed at one end of the rail 80.

The rotation guide 50 may include a boss holder 60 and a rotation holder70.

The supporting boss 42 may be inserted into the boss holder 60. The bossholder 60 may include a boss inserting portion 64 forming an insertionspace 65 into which the supporting boss 42 is inserted. The supportingboss 42 may be inserted into the boss insertion portion 64 through ahorizontal movement of the display assembly 10.

The supporting boss 42 inserted into the boss insertion portion 64 mayescape from the rail 80 to thereby be released from the rail 80. As aresult, the display assembly 10 may become rotatable.

The rotation holder 70 may be rotatable with respect to the boss holder60, and may be fixed on the rear surface of the display assembly 10.That is, the rotation holder 70 may be fixed on the rear surface of thedisplay assembly 10, and move and rotate together with the displayassembly 10. The boss holder 60 may be positioned within the rotationholder 70, and prevent the boss holder 60 from escaping from therotation holder 70. That is, the rotation holder 70 may be rotatablewith respect to the boss holder 60, while being not separated from theboss holder 60.

The boss holder 60 may include a boss holder body 62 formed in acircular shape so that the rotation holder 70 may rotate outside theboss holder 60. On the boss holder body 62, the boss insertion portion64 described above may be formed.

The rotation holder 70 may include a holder body 72 disposed along thecircumference of the boss holder 60, and a path forming portion 72forming a boss path 75 connecting the rail 80 to the boss insertionportion 64. The path forming portion 72 may form the boss path 75through which the supporting boss 42 passes when the supporting boss 42moves from the rail 80 to the boss insertion portion 64 due to amovement of the display assembly 10.

The rotation holder 70 may selectively disconnect the boss insertionportion 64 from the rail 80 when the display assembly 10 rotates. Whenthe supporting boss 42 is located on the rail 80, the boss path 75 maybe located between the boss insertion portion 64 and the rail 80.However, when the supporting boss 42 is inserted into the boss insertionportion 64, the display assembly 10 may become rotatable. The rotationholder 70 rotating together with the display assembly 10 may disconnectthe rail 80 from the boss insertion portion 64 through the holder body72.

With the configuration, the supporting boss 42 may be restricted by theboss insertion portion 64, thereby limiting a linear movement of thedisplay assembly 10.

The rotation guide 50 and the rail 80 may be fixed on the rear surfaceof the display assembly 10, although not limited thereto. For example,the display assembly 10 may be detachably mounted on the rear surface ofthe display assembly 10, and may be mounted at various positions on therear surface of the display assembly 10 according to the user'sconvenience.
